    Abstract: Systems and methods for screening unauthorized devices are provided. More particularly, a challenge that includes a first set of data can be generated. The challenge can require a browser of a requesting device to perform a browser task with respect to the first set of data to generate a second set of data. The challenge can be provided to the requesting device and a response to the challenge can be received. The response can include the second set of data generated by the browser of the requesting device through performance of the browser task. It can be determined whether the browser of the requesting device is an authorized browser based, at least in part, on the second set of data. Whether or not the requesting device is authorized to access a resource can be based, at least in part, on whether the browser is an authorized browser.

    Abstract: A search system extracts, for each property known to the system, historical information comprising data for itineraries associated with a partner system associated with the property. The search system determines, for each property-itinerary combination, an update frequency comprising based on historical information data. The search system extracts a history of user impressions of itineraries comprising the property. The search system determines a relative impression weight for each itinerary, an absolute impression weight for the property, and an expected impression weight of each property-itinerary combination. For each current property-itinerary combination, the search system determines a utility value based on the expected update frequency and expected impression weight to satisfy bandwidth constraints for each partner system. The search system schedules, for each partner system, queries for property-itinerary combinations having values greater than threshold utility value.

    Abstract: Systems and methods of verifying a user are provided. In particular, a request to engage in a verification process to gain access to an online resource can be received. The request can be provided by a first user device associated with a user. A validation request associated with a second user device associated with the user can be received. The validation request can include a device profile associated with the second user device. It can then be determined whether to validate the second user device based at least in part on the device profile. When it is determined to validate the second user device, the first user device can be granted access to the online resource.

    Abstract: Systems and methods of determining image characteristics are provided. More particularly, a first image having an unknown characteristic can be obtained. The first image can be provided to a plurality of user devices in a verification challenge. The verification challenge can include one or more instructions to be presented to a user of each user device. The instructions being determined based at least in part on the first image. User responses can be received, and an unknown characteristic of the first image can be determined based at least in part on the received responses. Subsequent to determining the unknown characteristic of the first image, one or more machine learning models can be trained based at least in part on the determined characteristic.
